Functional description

7.1 FM mixer 1

The FM quadrature mixer converts FM RF (65 MHz to 108 MHz) to an IF frequency of
10.7 MHz. The FM mixer provides high image rejection, a large dynamic range and
selectable mixer gain. The image rejection can be selected between low injection of LO
and high injection of LO via the I

C-bus independently of the band selection. A separate

RF input for weather band is available.

7.2 FM RF AGC

AGC detection at the FM front-end mixer input and the AM/FM IF AGC amplifier input,
both with programmable AGC thresholds. When the threshold is exceeded, the PIN diode
drive circuit sources a current to an external PIN diode circuit, keeping the RF signal level
constant.

Keyed AGC function is selectable via the I

C-bus and uses the in-band level information

from the IF DSP.

The AGC PIN diode drive circuit can optionally deliver a fixed current as a local function.
In AM mode, the AGC PIN diode drive circuit can be set to generate a fixed source current
into the external FM PIN diode circuitry.

7.3 Antenna DAA1 and DAA2

The antenna DAA1 measures the VCO tuning voltage and multiplies it with a factor
defined by the 7-bit DAA1 setting to generate a tuning voltage for the FM antenna tank
circuit. If a second FM tank circuit is applied, the tuning voltage can be derived from the
antenna DAA2 output. The antenna DAA2 measures the output voltage of the antenna
DAA1 and multiplies it with a factor defined by the 4-bit DAA2 setting.

7.4 AM LNA

The AM low noise amplifier is fully integrated.

7.5 AM RF AGC

The AM RF AGC is partially integrated. Detection is at the output of the AM LNA and at
the input of the AM/FM IF AGC amplifier, both with programmable thresholds. First the
integrated AGC reduces the gain of the LNA. After the LNA AGC, the PIN diode AGC
takes over by sinking a current via an external PIN diode.

In FM mode, the AM AGC can be set to a fixed attenuation.

7.6 AM mixer

The large dynamic range AM mixer converts AM RF (144 kHz to 26.1 MHz) to an IF
frequency of 10.7 MHz.

7.7 VCO and dividers

The varactor tuned LC oscillator together with the dividers provides the LO signal for both
AM and FM front-end mixers. The VCO has an operating frequency of approximately
160 MHz to 256 MHz. In FM mode the LO frequency is divided by 2 or 3. These dividers
generate in-phase and quadrature-phase output signals used in the FM front-end mixer
for image rejection. In weather band mode the LO signal is directly phase shifted to
generate the in-phase and quadrature-phase signals. In AM mode the LO frequency is
divided by 6, 8, 10, 16 or 20 depending on the selected AM band.

7.8 Tuning PLL

The tuning PLL locks the VCO frequency divided by the programmable divider ratio to the
reference frequency. Due to the combination of different charge pump signals in the
PLL loop filter, the loop parameters are adapted dynamically. Tuning to different
RF frequencies is done by changing the programmable divider ratio. The tuning step size
is selected with the reference frequency divider setting.

7.9 AM/FM IF AGC amplifier

The combined AM/FM IF AGC amplifier delivers a suitable IF signal for the ADC in the
IF DSP. The maximum gain of the IF AGC amplifier can be selected via the I

C-bus. The

gain of this amplifier is automatically adapted via interfacing signals from the IF DSP. The
IF AGC amplifier has three signal inputs, two for FM and one for AM. This allows the
application of multiple external filters, e.g. with different bandwidths.

The tuner circuit is controlled by the CONTROL register. Any data change in the
CONTROL register has immediate effect and will change the operation of the tuner circuit
accordingly. Transmitted I

C-bus data is not loaded into the CONTROL register directly

but loaded into a BUFFER register instead. This allows the IC to take care of tuning
actions freeing the microcontroller from cumbersome controls and timings.

Controlled by a state machine, the BUFFER data will be loaded into the CONTROL
register for new settings. However, at the same time the CONTROL data is loaded into the
BUFFER register. This register swap action allows a fast return to the previous setting
because the previous data remains available in the BUFFER register (see

Figure 6

and

Figure 7

Via MODE several operational modes can be selected for the state machine. MODE offers
all standard tuning actions as well as generic control for flexibility. The state machine
controls the tuner by controlling the internal I

C-bus data. Action progress is monitored by

the accompanying IF DSP via the AFSAMPLE and AFHOLD lines. This way, functions like
tuning mute and weak signal processing can be controlled complementary to the tuner
action.

The state machine operation starts at the end of transmission (P = STOP). In case a
previous action is still active, this is ignored and the new action defined by MODE is
started immediately. When only the address byte is transmitted, no action is started at all
(device presence test).

To minimize the I

C-bus transmission time, only bytes that include data changes need to

be written. Following the MSA byte the transmission can start at any given data byte
defined by the subaddress (SA) bits.

Furthermore, when writing the buffered range either the current BUFFER data or the
current CONTROL data can be used as default, controlled by the REGC bit:

With REGC = 0, any BUFFER data that is not newly written via I

C-bus remains

unchanged. In general, the BUFFER register will contain the previous tuner setting, so
this becomes default for the new setting. When only the MSA byte is transmitted
defining a tuning MODE with REGC = 0, the tuner will return to its previous settings
(see

Figure 6

With REGC = 1, the BUFFER register is loaded with data from the CONTROL register
first. This way, not written BUFFER data equals the CONTROL data. Since the
CONTROL register contains the current tuner setting with REGC = 1, the current
tuner setting is default for the new setting. When a tuning MODE action is defined with
REGC = 1, the tuner will keep its current settings (CONTROL = current) for all data
that is not newly written during the transmission (see

Figure 7

After power-on reset, all registers are in their default settings. The control signals for the
IF DSP are set to AFSAMPLE = HIGH and AFHOLD = HIGH (i.e. mute state). Any action
of the state machine will change this setting to a new one as defined by the bits
MODE[2:0].

8.2.1 Mode and subaddress byte for write

[1]

When the write transmission of a state machine command starts during a mute state of the state machine,
the sequences of the state machine start immediately with the actions which follow the mute period in the
standard sequence (see

Figure 9

Figure 11

Figure 13

Figure 15

and

Figure 17

[2]

References to mute are only used for better understanding. Muting is performed in the IF DSP controlled by
the tuner AFHOLD and AFSAMPLE lines.

[3]

In the modes preset and search the AM AGC time constant is set to fast during the period of complete
mute.

[4]

The AF update sequence can also be started by pulling the AFHOLD pin LOW. In this case the AF
information should be loaded into the BUFFER before. LOW period for a correct AF update timing:
t

LOW

> 20

s. Between the end of the I

C-bus transmission and the falling edge of the AFHOLD pulse a

17. Soldering

17.1 Introduction to soldering surface mount packages

There is no soldering method that is ideal for all surface mount IC packages. Wave
soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is recommended.

17.2 Reflow soldering

Reflow soldering requires solder paste (a suspension of fine solder particles, flux and
binding agent) to be applied to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement. Driven by legislation and
environmental forces the worldwide use of lead-free solder pastes is increasing.

Several methods exist for reflowing; for example, convection or convection/infrared
heating in a conveyor type oven. Throughput times (preheating, soldering and cooling)
vary between 100 seconds and 200 seconds depending on heating method.

Typical reflow temperatures range from 215

C to 260

C depending on solder paste

material. The peak top-surface temperature of the packages should be kept below:

Moisture sensitivity precautions, as indicated on packing, must be respected at all times.

17.3 Wave soldering

Conventional single wave soldering is not recommended for surface mount devices
(SMDs) or printed-circuit boards with a high component density, as solder bridging and
non-wetting can present major problems.

To overcome these problems the double-wave soldering method was specifically
developed.

If wave soldering is used the following conditions must be observed for optimal results:

Use a double-wave soldering method comprising a turbulent wave with high upward
pressure followed by a smooth laminar wave.

For packages with leads on two sides and a pitch (e):

larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be

parallel to the transport direction of the printed-circuit board;

smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the

transport direction of the printed-circuit board.

The footprint must incorporate solder thieves at the downstream end.

For packages with leads on four sides, the footprint must be placed at a 45

angle to

the transport direction of the printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.

During placement and before soldering, the package must be fixed with a droplet of
adhesive. The adhesive can be applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the adhesive is cured.

Typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250

or 265

C, depending on solder material applied, SnPb or Pb-free respectively.

A mildly-activated flux will eliminate the need for removal of corrosive residues in most
applications.

17.4 Manual soldering

Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage
(24 V or less) soldering iron applied to the flat part of the lead. Contact time must be
limited to 10 seconds at up to 300

When using a dedicated tool, all other leads can be soldered in one operation within
2 seconds to 5 seconds between 270

C and 320

17.5 Package related soldering information

[1]

For more detailed information on the BGA packages refer to the

(LF)BGA Application Note (AN01026);

order a copy from your Philips Semiconductors sales office.

[2]

All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the
maximum temperature (with respect to time) and body size of the package, there is a risk that internal or
external package cracks may occur due to vaporization of the moisture in them (the so called popcorn
effect). For details, refer to the Drypack information in the

Data Handbook IC26; Integrated Circuit

Packages; Section: Packing Methods.

These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no
account be processed through more than one soldering cycle or subjected to infrared reflow soldering with
peak temperature exceeding 217

C measured in the atmosphere of the reflow oven. The package

body peak temperature must be kept as low as possible.

[4]

These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the
solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink
on the top side, the solder might be deposited on the heatsink surface.

[5]

If wave soldering is considered, then the package must be placed at a 45

angle to the solder wave

direction. The package footprint must incorporate solder thieves downstream and at the side corners.

[6]

Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

[7]

Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger
than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.

[8]

Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered
pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by
using a hot bar soldering process. The appropriate soldering profile can be provided on request.

[9]

Hot bar soldering or manual soldering is suitable for PMFP packages.
